Any time I mention veganism, I feel the need to precursor the discussion with the fact that in no way am I suggesting that anyone is wrong for not practicing a plant-based diet or that it is necessarily healthier than an omnivorous one. Without a doubt, circumstances of food availability are different around the world, and regardless of our whereabouts, we all have personal versions of what we will and will not do or eat.
This article will be about plant-based sources of protein, not ignoring the fact that animal-based protein exists but offering alternatives for those who are interested. For those who aren’t, that’s your prerogative, and in this instance, no one is asking you to do anything differently or judging you for choosing to eat meat. Obviously, most of us—carnivores included— hope animals that become food are treated as humanely as possible, and obviously, animals have been eaten for millennia.
I felt the need to write this article because I’ve been watching a lot of permaculture videos with references to protein production, almost exclusively when talking about raising animals. I’ve heard very little about protein production in terms of plants. In reality, permaculture gardens are often wrought with plant-based protein, so for those who’d either like to supplement or replace their animal-based protein with plants. Here’s what you should be growing.
Legumes are amongst the most revered plants in permaculture, but this is usually for their nitrogen-fixing ability. We plant legumes in abundance both to revitalize depleted soils and to then keep them fertile. Some legumes aren’t edible, but there is a large selection of appetizing—both annual and perennial—options.
In addition to being good for the soil, they are also a great source of protein, with some varieties supplying as much per serving as beef, fish, or chicken. As a vegan, legumes—pulses—are a part of my everyday diet, and as a permaculturist, they are a large feature in nearly every garden design that I do, from annual beds to food forest.
Some of my favorite varieties to eat and grow include cowpea, pigeon peas, scarlet runner beans, and just about any kind available at a run-of-the-mill supermarket: white, red, black, pinto, garden pea, chickpea, spilt peas, lentils, and so on.
In the search for perennial sources of food, large trees are the centerpiece. We often talk about this in terms of fruit, but nuts come from trees as well. Though many of them take a while to provide yields, when they do, it is abundant and highly nutritious. What’s more is that they can be sized throughout the food forests, including the canopy, understory, and shrubs/hedges.
Nuts are a great source of protein and generally regarded as a healthy source of fat, which is often a concern for those on whole food (not processed) plant-based diets. As a vegan, nuts are my favorite snack, something easy and energizing to grab on the go, and as a permaculturalist, they are a great productive element in a food forest and, eventually, great lumber.
Some of the faster varieties include almonds, chestnuts, and hazelnuts, and some other obvious favorites are pecans (my ultimate choice), walnuts (may require buffer plants, like mulberry or black locust), and macadamias (tropical).
Generally, seeds are talked about in terms of what we can grow rather than a source of food, and of course, sowing is a huge part of what we do with seeds. First things first, we need to establish next year’s crop, at least with the annuals, but generally, many plants with healthy, edible seeds tend to produce them in abundance.
For some reason, seeds are overlooked in many diets, but they are a crazy nutritious source of protein, again with good fat (especially omega 3), as well as vitamins and minerals. As a vegan, I like to add them to salads, porridge, and bread, and as a permaculturalist, they are often secondary harvest from something or a good calorie-producer that also attracts pollinators.
Usually, with seeds, we think of pumpkin, sunflower, and sesame, and with the superfood movement, chia, flax, and hemp have also come onto this scene. Quinoa and amaranth, as well as several other seeds, are often lumped with grains because they can be prepared similarly.
Many people these days are avoiding grains, moving both their diets (the gluten-free thing) and gardens (the monoculture thing) away from them. However, they most definitely have their place in both, and though they are generally annual crops, they are well-established components of agricultural production, which means we eat them a lot.
Grains have a reputation for being a carbohydrate, but some whole grains are a surprisingly good source of protein. As a largely whole food vegan, I limit the amount of bread in my diet (my wife and I try to make the bread we eat), but I have rice and/or porridge on almost a daily basis, and as a permaculturalist, I can’t help but think about all that good mulch material left after a harvest.
In addition to bread, rice, and porridge, there are some great whole grains—rye, barley, millet—that we don’t see nearly enough. They can be planted as part of diverse systems and utilized in diverse diets.
Dark, Leafy Greens
Greens are a huge part of just about any garden. They are often easy to grow, and they can be harvested as they are needed. Greens are a great starter crops for newbies, as many can be grown in containers on a windowsill and provide results relatively quickly. Otherwise, many of them are marvelous because they tolerate (or even improve with) a little frost.
Dark, leafy greens should really be the staple of any healthy diet. They have a high protein count for a vegetable, and they are leading source of vitamins and minerals necessary in both plant-based and omnivorous diets. As a vegan or carnivore, they are vital to a full diet, and as a permaculturalist, they are a huge part of the kitchen garden, harvested daily.
Spinach, kale, mustard, chard, and collards have all really become staples in the vegetable market. There are also leafy (rather than heady) lettuces, like arugula, and wild edibles, like dandelion. I’ve also been lucky enough to regularly have leafy superfoods, such as moringa, katuk, and chaya.
And Just About Anything Else
When it comes to natural, whole foods, just about all of them provide some ration of protein, and though one potato or banana won’t provide a daily allowance, in a balanced diet, the accumulation of these small stores can quickly add up to a meaningful percentage of what a person needs. Broccoli has enough to be of significance, as do raisins and many dried fruits. In other words, with a balanced plant-based diet, getting enough protein is not a huge concern.
Also, for the vegan version of this, it’s worth noting that very few sources of plant-based proteins have all of the essential amino acids (soy is one of the few that does), but through a varied supply of protein, it’s very easy to get all of these. For example, rice and beans provides a complete protein, which explains why it is such a huge, functional part of vegetarian and low-income diets.
Ultimately, while protein production might habitually be a reference to raising animals for food, the truth of the matter is that our gardens, without ever considering the domesticated animals that may or may not be there, are likely full of protein. That production can undoubtedly be dramatically increased by including animals, but that source is definitely not the only unit by which to measure protein output. In fact, in terms of protein, it isn’t even necessary.
